1. A method for determining a stimulation setting for each electrode in a deep brain stimulation array including one or more electrodes, the method comprising:
- using brain geometry data to generate a discrete brain geometry grid;
identifying one or more grid points in the discrete brain geometry grid, the one or more grid points representing a target tissue to be activated by stimulation through the one or more electrodes;
calculating a maximum activation function value for each of the one or more grid points using an estimated voltage distribution of the stimulation of the one or more electrodes;
constructing a maximum curve for the discrete brain geometry grid from the maximum activation function value of each of the one or more grid points;
optimizing a set of stimulation settings for each of the one or more electrodes using one or more optimization methods such that an actual activation curve for the discrete brain geometry grid is as close as possible to the maximum curve of the discrete brain geometry grid; and
providing, to a pulse generator capable of delivering therapy via each of the one or more electrodes, the set of stimulation settings for each electrode.

Abstract
Systems, methods and apparatus for determining and/or programming stimulation settings for a pulse generator capable of steering current to a deep brain stimulation array are disclosed. Individual patient brain geometry and lead specific geometry data can be used to generate a maximum activation function curve. Optimization methods can be used to find stimulation settings that are as close as possible to achieving the value of the maximum activation function curve.
